Originální abstrakt

A new test method of set fibre concrete homogeneity in finished steel fibre-concrete structure is described in this contribution. The method is based on measurements of the changes in magnetic field strength of permanent magnets which are induced by a change of wire distribution in steel fibre-concrete structure. It is evident from the method described in this contribution that the test is characterized as a local failure test using small diameter core drill. It is a semi-destructive method. Its application in practice does not affect safety and reliability of steel fibre-concrete structures. Additionally to the method described, an example of its application for the assessment of fibre concrete homogeneity of the segmental tunnel lining parts is described. The results of partial measurements give both information about fibre concrete homogeneity in a segment and a number and a selection of points for homogeneity measurements which are subject to the size and the production method of such segment.
